When the story starts, Korg tells a tale about Fat Thor getting in shape and fighting alongside the Guardians of the Galaxy. This provides a substantial amount of exposition. Thor shifts his focus to Gorr the God Butcher, a brand-new menace that has the potential to ruin the planet.

In order to combat Gorr the Butcher, who threatens to kill them all and has motivations based only on retaliation against the Gods, Thor teams up with Jane Foster aka Mighty Thor (more on that in a moment), King Valkyrie, and Korg. With the expected CGI creatures and a massive battle at the conclusion, the fate of the universe is on the line.

Early on, we meet Jane Foster, a scientist who has been conducting research that has been "saving the world" on Earth, and also Thor's former girlfriend. She is, however, also suffering from cancer and receiving chemotherapy.

She also begins studying Mjolnir (Thor's broken hammer) and how it can give her stamina and health, thinking the broken pieces of Mjolnir are beckoning to her and might cure her cancer.

Her search to save herself along with her general character makes her worthy to take up Thor's hammer for herself, becoming another version of Thor.

The jokes are a mixed bag at best, which only serves to exacerbate the lackluster character development. Although there are a few good laughs, everything feels so ridiculous and simplistic that it defies belief. Additionally, the fact that the comedy frequently undermines the overall movie's stakes doesn't help. Jokes are frequently exchanged throughout, even during the decisive showdown with Gorr, entirely negating the menace.

Fans of the previous entry into the Thor series (Thor: Ragnarok) are most likely to enjoy this one. But, the tone may or may not appeal to everyone who typically enjoys MCU movies.
